The Dynamic Cone Penetrometer apparatus was originally developed by the TRL-UK Transport Research Laboratory. It is used for In-rapid in situ measurement of structural properties of existing road pavement constructed with unbound materials. It consists of an 8 kg weight dropping through a height of **5 mm and *0° cone having a diameter of *0 mm. DCP measurements can be made down to a depth of approximately **0 mm. Correlations have been established in earlier work (Van Vuuren, Klein and Van Herden, Smith and Pratt) between the TRL penetrometer and CBR (California Bearing Ratio) so that results can be interpreted and compared with CBR specifications.
